This is my first review of the MAGICRIG A7SIII camera frame and I will update as soon as I use it. I think from what looks like premium aluminum I like that it has lots of 1/4' and 3/8' mounting points and a couple of A RR i style mounts to mount lots of accessories like the ball joint head, the rod clamp or the magic to assemble hand. In addition, you can shoot from different angles and it is very easy to hold in hand. Overall I think the build quality is amazing for the price. In my opinion this is the best A7SIII cell I have found so far. I highly recommend them.
